Abstract

The invention discloses a heat-dissipating fastener fixing structure and a tool for demounting a heat-dissipating fastener. The heat-dissipating fastener fixing structure comprises a chute and a heat-dissipating fastener body. The chute is formed at the back of a heat-dissipating device, and a fastening groove is formed above the chute. The heat-dissipating fastener body is a U-shaped plate with a long side and a short side. A section of inwards-recessed arc-shaped face is arranged on the long side of the heat-dissipating fastener body. The short side of the heat-dissipating fastener body can be fastened in the chute. The arc-shaped face on the long side of the heat-dissipating fastener body can be pressed on a power element at the back of the heat-dissipating device. A gap is formed between the long side of the heat-dissipating fastener body and the bottom side of the U-shaped plate. The heat-dissipating fastener fixing structure has the advantages that demounting of the heat-dissipating fastener body is facilitated, assembly efficiency is obviously improved, reliable fit of the power element and the heat-dissipating device is guaranteed, uniformity in assembly is good, process steps such as punching of the heat-dissipating device and shaping of the power element are reduced, and the heat-dissipating fastener fixing structure is simple in structure, convenient to process, high in assembly efficiency, good in uniformity and reliable in fixation.

Description

technical field [0001] The patent of the present invention relates to a heat dissipation structure for electronic products, specifically a heat dissipation clip fixing structure and a tool for disassembling the heat dissipation clip. Background technique [0002] With the continuous development of electronic technology, the technology of high-power IGBT, field effect transistor, thyristor, bipolar transistor and other power devices is becoming more and more mature. Based on this, electronic ballasts, switching power supplies, power amplifiers, and electric vehicle control The application of electronic products such as appliances is also more extensive. In the design and manufacturing process of these products, bolts or traditional U-shaped spring clips have been used to fix power devices and heat sinks; [0003] When using bolts, it is required that there must be a hole corresponding to the power device on the heat sink, so that the bolt passes through the heat sink and the...
